' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim ftp As New Chilkat.Ftp2

ftp.Hostname = "ftp.example.com"
ftp.Username = "login"
ftp.Password = "password"

' Set the HTTP proxy server properties.
' This is to connect via HTTP/1.1 using CONNECT method
ftp.HttpProxyHostname = "192.168.1.127"
ftp.HttpProxyPort = 8080

' If the proxy server requires authentication...
ftp.HttpProxyUsername = "myProxyUsername"
ftp.HttpProxyPassword = "myProxyPassword"

' FTP over an HTTP proxy requires that FTP Passive mode be used
' for data transfers. It is not possible to use non-passive (active) mode
' for FTP over HTTP.
ftp.Passive = True

' Connect and login to the FTP server.
Dim success As Boolean = Await ftp.ConnectAsync()
If (success <> True) Then
    Debug.WriteLine(ftp.LastErrorText)
    Exit Sub

' Change to the remote directory where the file will be uploaded.
